Thanks for posting Larry,
one very key point I see is correct; exact master link.

I broke a chain very far from anywhere a couple of years ago in Moab, Utah. The master link, I had in my pack, was just a little bit too small to get the clip on it. I struggled for an hour trying to get the link to work with limited tools on the trail. No way would it work. So about to give up and cry, cuss and pray( crisis moment for sure), a stray rider came by with the correct sized link. Took me two minutes to fix the chain with new link and we headed back to camp.

Still don't know how I had the wrong size link in my pack? Now I carry two spares( one for stray riders on the trail)
